The 'Goop' founder can't wait to marry her fiancé Brad Falchuk and is excited about "everything" to do with her big day.
She said: "I’m excited about everything! I’ve never had a wedding before. So even though I’m 45, I sort of feel like a 21-year-old."
The 45-year-old actress is enjoying getting her friends involved in planning too.
She told People magazine: "We haven’t really started making any formal plans [but] it’s kind of fun to talk about with my girlfriends. They send me pictures of dresses - they’re as excited about it as I am. It’s pretty cute."
Meanwhile, Gwyneth previously admitted she doesn't imagine she'll have a "big" wedding with Brad and instead would prefer a low-key ceremony.
She said: "I think I'm [too] old to have a big wedding and a big ole white dress and all that. I gotta dial it back."
Despite her marriage looming, Gwyneth - who has Apple, 13, and Moses, 11, with her ex-husband Chris Martin - has confessed she has a fear of intimacy.
She explained: "It's a life-long project. I think that there are certain people who have a really hard time with intimacy. I always say, I'm a good sister. I'm a good daughter. I'm a good girlfriend. I'm a good mother. That romantic slice of the pie chart of my life has always been where I find my deepest work ... I just am trying to towards intimacy instead of being scared of it and I'm really lucky that I found a partner that's patient and loves me and is willing to help me with my process."
